213 × 88 × 330 mm 3 kg
(8-3/8 × 3-1/2 × 13" 6.6 lbs)
The 7560 (6-1/2 digit display) Series is a high-accuracy,
high-speed sampling bench-top digital multimeter lineup using a YOKOGAWA-original A/D converter (feedback pulse
width modulation method), which features excellent stability, high noise immunity and linearity. In addition to the basic features, an optional IC memory card capable of storing
8,000 data, GP-IB or RS-232-C interface and versatile measurement functions allow these multimeters to be used in diverse fields of applications, from bench to system uses.

■ High-speed sampling
• 7560 Series: 333 times/s
The feedback PWM A/D converter, which includes a
new counting system, allows a high-speed response
without changing any excellent features.
The sampling rate of 40 times/s can be obtained even
with a 5-1/2 digit display. The 7560 Series offer high system throughput with a large memory capacity, highspeed auto-ranging, programmable sampling interval,
and integrating time.
■ GP-IB or RS-232-C interface (standard)
■ High accuracy, and excellent stability and linearity
• 7560 Series
DC voltage accuracy : ±0.003% of rdg ± 15 digits
(90 days, 23 ± 5°C)
OHM accuracy
: ±0.009% of rdg ± 30 digits
(90 days, 23 ± 5°C)
■ A large memory capacity of 8,000 data by using IC
memory card
The 7560 Series can store 1,000 measured data by using
internal memory (or 8,000 data by using an optional IC
memory card).
This allows high-speed sampling without being affected
by transmission capacity via a communication bus.
Data can then be transferred to a controller after completing measurements.
These storage functions allow DMM’s to be used as
high-speed data logger.
The following functions are available with communication interface.
● Functions executed by panel key operation
● Measured data output
● Panel-set data output
● Stored data output
● Status byte output
■ An input-site change between front and rear panels
7560 Series has the input terminal for the voltage and resistance between front and rear panels.

■ MEASURING RANGE
• Auto Range Mode
When the display data increases more than 20,000/200,000,
the range is automatically changed (increased), whereas
when the display data goes down to less than 1,800/18,000,
the range is automatically changed (decreased).
■ TIME DELAY FUNCTIONS (TD)
The time interval between a trigger signal generation and the
sampling can be set from 0 to 60 minutes.
This allows accurate measurements when a signal source
has dead-time or the measurement circuit shows a first-order
lag response.
Input
• Manual Range Mode
If the measuring range exceeds upper-limit setpoint, –oL–
(overload) is displayed.

■ SAMPLING FUNCTIONS
• N Reading Mode (N RDGS)
Data are sampled in the cycles set by the integral time and
measuring intervals.
■ TRIGGER FUNCTIONS
The following three ways are available for generating trigger
signals.
• Press the TRIG key on the front panel.
• Input a contact signal or TTL logic signal to the I/O signal
connector (pin No. 1).
• Send the “E” or GET command through GP-IB or RS-232-C.
In STORE mode, triggering performs three types of operations according to measurement modes as follows:
• In AUTO mode, data are written leaving NS-1 data before
generating trigger signals and the STORE mode is automatically turned OFF when memory capacity is full. Amounts of
data that are written depend on the built-in memory or IC
card memory. (PRE-TRIGGER FUNCTION)
• In SINGLE mode, sampled data is stored every time a trigger signal is generated. If NS data that are preset are stored,
STORE mode is automatically turned OFF. (PRESET
COUNTER FUNCTION)
• In N RDGS mode, each NS data is stored every time a
trigger signal is generated. STORE mode is in halt status until
the next trigger signal is generated. The STORE mode is automatically turned OFF when memory capacity is full.
In RECALL mode, data are recalled whenever a trigger signal
is generated according to measurement mode. In AUTO
mode, data are automatically recalled at measurement intervals which have been set at the time of recall.
Time Delay
■ NULL FUNCTIONS (NULL)
Y = X – X0
where; X0 : initially set value (NULL value)
Y : computed value
X : measured value
Reset an initially set value (data being displayed) to zero as a
NULL value.
Thereafter a value subtracted by a NULL value is displayed
as a measured value. This null function is used to eliminate
leadwire resistance or cancel initial values.
■ AVERAGING FUNCTION (AVG)
The AVG function is used to average the measured data.
This comes into effect when noise components or variation
of measured data at high-speed sampling must be eliminated
from the measured value.
The calculation expression is given by:
Y = (XAT + XAT-1 + .... + X1)/AT
where; AT : 2 to 100 (number of average data)
X : measured value
Y : computed value

■ MATHEMATICAL FUNCTION (MATH)
■ STORING FUNCTION (STORE)
• Scaling
The scaling function serves not only to indicate a multiple
with preset multiplying factors but also to determine deviation from a preset reference value.
Store the measured data in built-in memory or IC card
memory. When an IC memory card is installed, the measured data is stored in the IC card memory.
where ; Y : computed value,
X : measured value,
A and B : constants,
where :
–1,999,999E9 ≤ A ≤ 1,999,999E9
–1,999,999E9 ≤ B ≤ 1,999,999E9, B ≠ 0
• Decibel
The decibel function serves to perform logarithmic operations (common logarithms) for measured values (or null or
averaging values).
Y = C x log10 (X/D),
where ; Y : computed value,
X : measured value,
C and D : constants,
where :
–1,999,999E9 ≤ C ≤ 1,999,999E9
–1,999,999E9 ≤ D ≤ 1,999,999E9, D ≠ 0
• Comparator
The comparator function compares a measured value (or
null or averaging values) with the reference value to determine which value is larger or smaller if the measured value
is within the limits.
X ≥ H ... High
H > X > L ... Pass
L ≥ X ... Low
X : measured value,
H and L : constants,
where :
–1,999,999E9 ≤ H ≤ 1,999,999E9
–1,999,999E9 ≤ L ≤ 1,999,999E9
If H and L are set to the same value, whichever value is
larger or smaller is indicated. And the computed result is
displayed and output to outer computer pin.
The STORE function has three operations depending on
measurement modes as follows:
• In AUTO Mode
In AUTO mode, press the STORE key to store data in
memory. If the memory overflows, the oldest data are automatically erased and replaced by the newest data. If the
STORE mode is OFF, data is no longer stored. In AUTO
mode, if a trigger signal is generated, data can be written to
the memory, leaving NS-1 data before generating a trigger
signal. (PRE-TRIGGER FUNCTION)

Pre-trigger Function
• In SINGLE Mode
In SINGLE mode, data measured in each sampling cycle are
stored every time a trigger signal is generated. If NS data that
was preset are stored, STORE mode is automatically turned
OFF. (PRESET COUNTER FUNCTION)
• In N RDGS Mode
NS data are stored every time a trigger signal is generated.
The STORE mode is in halt status until the next trigger signal
is generated. If the memory overflows, the STORE mode is
automatically turned OFF. (POST TRIGGER FUNCTION)

• In N RDGS Mode
NS data are output at the preset measurement intervals
whenever a trigger signal is generated. Then the mode is in
the halt state. If the trigger key is pressed again, recalling of
data is started. If the final data are output, the recall mode is
automatically turned OFF.
■ IC MEMORY CARD
The 7560 Series are the first DMM with IC memory card
(optional).
IC memory card allows you to:
• Save up to 8,000 measured data.
• Functions, ranges, and mathematical functions ON/
OFF, sample speed and so on, are saved.
• Setting programs using the front panel keys and measured data can be stored.
• Automatic loading of setting program at power ON.
7560 Series get the more applications by the above IC
memory card functions.
The data format of IC memory card is compatible with that
of YOKOGAWA LR Series Recorders, so the measured data
can be recorded in analog form on strip chart.

Data
• In SINGLE Mode
Data are recalled every time a trigger signal is generated.
When the final data are output, the recall mode is automatically turned OFF.
TRIG
• In AUTO Mode
Data are output at the preset measurement intervals. When
the final data are output, the recall mode is automatically
turned OFF.
• Automatic Loading
IC memory cards allow measurement parameters and conditions to be set without using the panel keys. If a memory
card containing set data is inserted and then the power is
turned ON, the memory contents are automatically read and
programmings are set.
This is very useful for measurements that are repeated under
the same conditions, and this can be a powerful support tool
such as in the production line.
• Programming Function
If an IC memory card is installed, up to 20 steps can be programmed either by front panel key operations or via communication interfaces. The required functions, ranges, and
mathematical functions can be set ON or OFF, and multichannel measurements can be performed in a combination
with scanners.
END
■ RECALL FUNCTION (RECALL)
Recalls the stored data from the memory. The recall functions are as follows:

■ CALIBRATION FUNCTION
The multimeters can be calibrated either by front panel key
operations or via communication interfaces. The multimeters are calibrated without opening the case and any special calibration skills.

■ AUTO ZERO FUNCTION
AUTO ZERO (AZ) compensates for zero drift which will be
generated in the internal circuit every time sampling is executed. In high-speed sampling mode, measurement time is
decreased by eliminating AUTO ZERO function.
